Microcomputer based sulfur analyzer, also known as automatic sulfur analyzer, automatic sulfur analyzer, microcomputer based sulfur analyzer, microcomputer based sulfur analyzer, some companies also refer to it as rotary table sulfur analyzer, fully automatic sulfur analyzer, etc

It belongs to a vertical furnace structure and uses a corundum crucible to place coal samples.

· oneAdopting standards:

· GB/T 214-2007 "Method for determination of total sulfur in coal"

· GB/T 483-2007 General Provisions for Coal Analysis Experimental Methods

· GB/T 387-1990 "Determination of sulfur content in dark petroleum products - Tube furnace method"

· twoScope of application:

· Suitable for the determination of total sulfur in materials such as lignite, bituminous coal, anthracite, coke, dry coal samples of coal water slurry, and heavy oil in industries such as electricity, coal mining, metallurgy, chemical engineering, cement, geological exploration, and scientific research institutions.

By adding samples, it is easy to implement the queue insertion function and dynamically adjust the sample making sequence. How to implement it? Please refer to the introduction for details

3、 Technical parameters:

1: The number of samples ranges from 1 to 24 (during the testing process, samples can be dynamically added at will, and the functions of queuing up again and dynamically adjusting the sample queue and sequence can be achieved)

2: Dimensions 500mm × 400mm × 730mm

3: Net weight of the instrument is 30kg

(The following technical parameters are not only available for this instrument, but also for other types of sulfur analyzers in our company.)

1: Testing principle Coulombic titration method

2: Sulfur resolution of 0.001% (higher than 0.01% of other peers)

3: The sulfur measurement range is 0.1% to 40% (if it exceeds the range, please contact the special model by phone)

4: Sample weight 50.0mg (input range 0.1 ㎎~99.9 ㎎) Ultra high sulfur content samples can be weighed less, while sulfur content samples can be weighed more to facilitate analysis of other substances

5: Test time 4-8 minutes (automatic determination of titration endpoint, specific time depends on sample type and weight)

6: The test temperature is 1150 ℃ (coal coke) and 920 ℃ (oil). The temperature control range is 400-1200 ℃, which is convenient for other analyses

7: Temperature control accuracy ± 2 ℃.

8: Precision meets GB/T214-2007

9: The accuracy is within the allowable error range of the standard sample and better than the national standard

4、 Performance characteristics:

1: Adopting the modular design concept, the integrated rotary automatic sample delivery mechanism, vertical high-temperature cracking furnace, electrolytic cell, agitator, air purifier and other system components are assembled in one box. The concept is innovative and the structure is clever, making the instrument easy to maintain and debug, and the appearance is beautiful and elegant.

2: Although the instrument does not have a built-in electronic balance, it requires the laboratory technician to manually weigh the sample. But the automatic input of sample weight can be achieved by pressing the button when weighing the sample through an external electronic balance. The entire testing process after sample installation can be unmanned and automatically completed by the instrument: fully automatic continuous sample delivery, fully automatic coulombic measurement, fully automatic control of function switches, and automatic storage of test results in the database...

3: The constant current source electrolysis method is implemented by the program to calculate the Coulomb titration integral. The program comes with a dedicated overall coefficient calculator, and system errors are corrected by the software itself. The test results are better than the national standard, with good repeatability and high accuracy.

4: The system design has a dedicated fault detection task program. When the instrument is working, it will monitor the various functional components of the system in real time and provide fault diagnosis and prompt functions. In addition, there is a powerful debugging menu that greatly facilitates the diagnosis and troubleshooting of faults.

5: The microcomputer testing software fully supports Windows 9X and Windows XP platforms, with high system stability. The human-computer interaction interface is user-friendly and easy for operators to learn and use. Can be connected to the internet to achieve remote data sharing, facilitating data sharing management.

6: The hardware of the control system adopts the ARM series microcontroller from the United States, and the control software is written under the multitasking operating system UC/OS-II, ensuring stable and reliable instrument performance and strong anti-interference ability.
